Answer:
33 °C
Step-by-step explanation:
The bigger number is the maximum temperature.
Let’s call it T₂.
Then T₂ = 31 °C
=====
The smaller number is the minimum temperature
Let’s call it T₁.
Then T₁ = -2 °C
=====
The difference be the maximum and minimum temperature is
Diff = T₂ -T₁ Insert the values
Diff = 31 – (-2)
When you see a minus sign followed by a negative sign, turn them both into plus signs.
Then
Diff = 31 + (+2)
Diff = 31 + 2
Diff = 33 °C
